Fishing Korsujärvi: what the data says
54-acre lake in Finland. The lake tops out around 33 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
The drawn water covers 54 acres wrapped in 1.9 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. About 59% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.
